I am looking at force vs. time graphs on a project i am
working on and i have seen several of them look like this:

what i would like to do is take the data which produces

is it possible to limit rand value so that it doesn't repeat?
Which each of these file is only play one time
a{3} = {audio, fs};
a{4} = {audio, fs};

I am trying to create a half sample delay in a SIMULINK
model but getting of rate conversion problems.
The system is a continuous-time delta-sigma modulator, where
I  set the sample time very low for blocks which work in

I am trying to read fairly large chunks of analog data from
my National Instruments board (PCI 6110).  I look at the
'MaxBytes' using the 'daqmem' function, and I have plenty of
space for what I am trying to acquire (as I define in

After I changed the data type from floating point to fixed
point in my m file, the run time has increased by almost 100
times. Is this expected?
Cheers,

N = single(randn(5000,5000));
I'd like to create a single precision randn matrix without going via
the double. Any way to do that?

Does anyone know what type of file a .ike is?  Also, how
can you open it in MATLAB to get the data out?  Thanks.. =)

Can you cast a 'cell' object into a 'double' ? I want to take a user input from a dialog box (of type cell) and use that for further calculations. But you can't use a cell object type for calculations I think....or I am I wrong?

I'd like to make a plot with the axes as "crosshairs", i.e., instead of
having the X and Y axes (with tick marks, etc) at the left of and below
the plot, I'd like them to be in the middle of the plot, with the X axis
at Y=0, and the Y axis at X=0.  I see that the axes have ...

I have developed a GUI in which there is a Background Image
over which I plot the movement of sensor nodes.
function varargout = ver1GUI(varargin)
% VER1GUI M-file for ver1GUI.fig

I am looking to plot a line plot of a function (say, x^2)
and a scatter plot of various data points on the same
figure.  Is there a way to do this?
Perhaps it involves using the "hold on" command?

If I were to do something like this:
a = 3
b = 2
syms x

I have timeseries data and various intervals (1-minute, 15-minute) and would like to be able to resample these datasets so they are both at a half-hour timestamp.  An earlier post indicated that the decimate() would be a reasonable solution.  I've been unable to make this ...

plz excuse my english.
I have matlab version 6.5 and i have two problems:
1) How to solve equation F(x,y)=0? Is there in matlab any tool for that?
2)I cant find problem in my function, so plz check it:
